cdnjs Library Repository

    

cdnjs is the repository mirroring all library assets on cdnjs.cloudflare.com.

Thomas Davis and Ryan Kirkman created cdnjs, Drew Freyling and Peter Dave Hello are maintainers. Juan Gallardo is our community moderator.

cdnjs will host any production version of any JavaScript/CSS library, subject to license permissions.

• Libraries must have notable popularity: 100 stars/watchers on GitHub, or more than 500 times download per month on npm stats are both good examples, but as long as reasonable popularity can be demonstrated the library will be added.
• Beta, release candidate and alpha releases are not usually considered ready for full production status. Requests for pre-release versions of libraries may be declined after peer review.
• We'll accept beta, release candidate and alpha releases if you are using our npm/git auto-update mechanism, if you really want it, please setup auto-update for that lib.

Please raise a new pull request for new library additions and existing library updates, following the instructions below.

IMPORTANT

• Please read the instructions about sparseCheckout and shallow clone before any git clone operation to this huge repository: documents/sparseCheckout.md
• All new libraries hosted on CDNJS should have an official public repository or npm package, and the officially pre-built distribution file(s) should also be there, so that we can apply the auto-update mechanism on that lib.
• Now CDNJS supports adding a library by a single package.json, you just need to add a valid CDNJS package.json with npm/git auto-update config, and remove its version field in package.json, then we'll handle the remaining works.
  • Notes that you should have a filename to point to the main file of a lib, if that file is not minified, please still use filename.min.js or filename.min.css structure naming, we'll do the minify job.

Adding a new or updating an existing library

cdnjs relies on user-submitted pull requests and automatic updating via npm or git repository to populate and update libraries.

To add a new library, or update an existing library outside of npm/git, start by forking the cdnjs repo to your own GitHub account.

If you're adding/modifying outside of the GitHub browser interface, for example on the command line or with the GitHub desktop application, you will need to additionally install node(node.js) locally, so that you can run the test or utils under tools locally.

When you have forked the cdnjs repo, add your library to it. Libraries are stored in the ajax/libs directory. Each library has its own subdirectory of ajax/libs and each version of the library has its own subdirectory of the library directory name, for example:

/ajax/libs/jquery/2.0.0/

@IonicaBizau wrote a NodeJS command line tool for automating the adding process of a new library. This tool is named cdnjs-importer and it's open source

For more information regarding this importer, please check out the repository documentation.

Conventions

You should consider the following when adding to or updating the library, so that we can keep our project neat, clean and clear:

• Filenames should not include a version number.

  • This is OK: useful.min.js, but this is not: useful-2.0.1.min.js.

• JavaScript & CSS files should be minified to reduce network traffic and browser overhead.

  • If the library doesn't already provide a minified version, cdnjs's preferred JavaScript minifier is UglifyJS

• If you are updating a library, please try to maintain consistency with the existing file and directory structure.

  • There will be occasions, particularly with major version increments, where this is not practical.

• You should sync your local repository with our master branch as new as possible, try to make the commits' parent be new.

• Please use git pull --rebase instead of git pull, use git rebase upstream/master instead of git merge upstream/master, so that we can avoid of meaningless merging.

• Only do one meaningful thing in one commits, don't mix different things into the same commit, like add two libs in a commit.

• Every commits should be meaningful, don't cut one thing into multiple commits, like add a lib in 3 commits.

• Inspect your work by git diff & git status before commit your change.

• Inspect your commit by git log --stat & git log -p before sending a pull request.

Create or update package.json

Each library has a corresponding package.json, written in npm format (see test/schemata/npm-package.json for details or use another package.json to crib from - it's pretty self-explanatory), and we use filename field in package.json to point to the mainfile of a lib, this field will be required. When an existing library is updated, the details in package.json should be updated where required.

For example, if a new version of the library is added, the version number may need changing. Likewise, if you're adding npm update information to a library, this is done in package.json.

Run npm test to check all is well

If you're updating the library outside of npm or the GitHub browser, you should run npm test from the library directory to ensure everything is OK.

If you run npm test and see no errors, all is well; resolve any errors before you raise your pull request and re-run npm test to ensure everything works.

If you see an error then run npm install before running npm test:

vows: command not found
npm ERR! Test failed.  See above for more details.
npm ERR! not ok code 0

Pull request pre-flight checks

• Have you complied with our conventions?
• Have you followed the library directory structure?
• Does a valid and accurate package.json exist for the library?
• Have you minified JavaScript and CSS?
• Did npm test check out OK?

...if so, great! You're ready to raise a pull request.

Raising a pull request

Please restrict your pull request to one library. You can include >1 version/release of a library in a single pull request.

From a maintenance standpoint, it's much more straightforward to process pull requests where there is one commit for one library.

In your pull request title, tell us what you're doing.

• If you are the author of the library, please add [author] to the pull request title.

• If you are adding a new lib, please add [new] to the pull request title.

Please include the following in your pull request:

• The origin of your new files
  • e.g., where you downloaded the version from

A URL is ideal. Providing the origin of your files is very helpful as the cdnjs project is peer-reviewed. Practically speaking, it also helps us process your pull request more efficiently, which means your files go live sooner. Help us and we'll help you back.
